-there is more to an economy than manufacturing. Using manufacturing metrics to rate an economy is like scoring a soccer game based on how far your players run: in some contexts correlated with “winning” but in others it’s not. -gold is not a good currency or basis for monetary policy. -these ideas only sound self consistent without economic context.
But solution point 1 — brain drain the rest of the world — is an absolutely first rate policy. The fact that the US requires newly-minted PhDs educated here to get a different visa or leave is absolutely self-defeating. We should be welcoming skilled immigration from everywhere.
For my money, you’re better off reading Krugman, Brad Delong, and (my personal favorite) Michael Pettis. I’ll read Geohot when it’s about engineering or self driving cars.
